FIELD

The present disclosure relates to novel compounds that are inhibitors ofthe kinase IRAK4. The disclosure also relates to methods for preparingthe compounds and to pharmaceutical compositions comprising suchcompounds.

BACKGROUND

Interleukin-1 receptor-associated kinase-4 (IRAK4) is a serine-threoninekinase which acts as a mediator in interleukin-1/Toll-like receptor(IL-1/TLR) signaling cascades. More particularly, IRAK4 is involved inactivation of adaptor protein myeloid differentiation primary responsegene 88 (MyD88) signaling cascades and is hypothesized to play a role ininflammatory and fibrotic disorders, such as rheumatoid arthritis (RA),inflammatory bowel disease (IBD), gout, Lyme disease, arthritis,psoriasis, pelvic inflammatory disease, systemic lupus erythematosus(SLE), Sjogren's syndrome, viral myocarditis, acute and chronic tissueinjury, non-alcoholic steatohepatitis (NASH), alcoholic hepatitis andkidney disease, including chronic kidney disease and diabetic kidneydisease. In addition, IRAK4 plays a role in certain cancers and ishypothesized to play a role in inflammation associated withgastrointestinal infections, including C. difficile. Signaling throughIL-1R/TLR results in the activation of MyD88 which recruits IRAK4 andIRAK1 to form a signaling complex. This complex then interacts with aseries of kinases, adaptor proteins, and ligases, ultimately resultingin the activation of nuclear factor kappa-light-chain-enhancer ofactivated B cells (NF-κB), activator protein-1 (API), cyclicAMP-responsive element-binding protein (CREB) and theinterferon-regulatory factors (IRFs), including IRF5 and IRF7, inducingthe generation of pro-inflammatory cytokines and type I interferons.

Therefore, inhibitors of IRAK4 may be useful in the treatment ofinflammatory and fibrotic disorders, such as rheumatoid arthritis (RA),inflammatory bowel disease (IBD), gout, Lyme disease, arthritis,psoriasis, pelvic inflammatory disease, systemic lupus erythematosus(SLE), Sjogren's syndrome, inflammation associated with gastrointestinalinfections, including C. difficile, viral myocarditis, acute and chronictissue injury, non-alcoholic steatohepatitis (NASH), alcoholic hepatitisand kidney disease, including chronic kidney disease and diabetic kidneydisease.

In addition, certain cancers, including lymphomas, may contain one ormore mutations in the MYD88 adaptor protein, leading to a constitutivelyactive signaling cascade that may promote survival of tumor cells.(Kelly et al., IRAK4 inhibitors for autoimmunity and lymphoma, J. Exp.Med. 2015 Vol. 212 No. 13 2189-2201)

Therefore, an inhibitor of IRAK4 may be useful in the treatment ofcancers, including lymphomas.

There are currently no approved IRAK4 inhibiting pharmaceuticals.Therefore, it would be useful to provide an IRAK4 inhibiting compoundwith properties suitable for administration as a pharmaceutical agent toa mammal, particularly a human. Considerations for selecting apharmaceutical compound are multifactorial. Compound characteristicsincluding on-target potency, pharmacokinetics, pKa, solubility,stability (e.g., metabolic stability) and off-target liabilities(including potential cardiac toxicity), as well as potential drug-druginteractions are frequently profiled.

DETAILED DESCRIPTION OF THE INVENTION Definitions

The following description sets forth exemplary methods, parameters andthe like. It should be recognized, however, that such description is notintended as a limitation on the scope of the present disclosure but isinstead provided as a description of exemplary embodiments.

A dash (“-”) that is not between two letters or symbols is used toindicate a point of attachment for a substituent. For example, —C(O)NH₂is attached through the carbon atom. A dash at the front or end of achemical group is a matter of convenience; chemical groups may bedepicted with or without one or more dashes without losing theirordinary meaning. A wavy line drawn through a line in a structureindicates a point of attachment of a group. Unless chemically orstructurally required, no directionality is indicated or implied by theorder in which a chemical group is written or named.

The prefix “C_(u-v)” indicates that the following group has from u to vcarbon atoms. For example, “C₁₋₆ alkyl” indicates that the alkyl grouphas from 1 to 6 carbon atoms. C₀ indicates that no carbons are present,or in other words, a bond to the next substituent.

Reference to “about” a value or parameter herein includes (anddescribes) embodiments that are directed to that value or parameter perse. In certain embodiments, the term “about” includes the indicatedamount ±10%. In other embodiments, the term “about” includes theindicated amount ±5%. In certain other embodiments, the term “about”includes the indicated amount ±1%. Also, to the term “about X” includesdescription of “X”. Also, the singular forms “a” and “the” includeplural references unless the context clearly dictates otherwise. Thus,e.g., reference to “the compound” includes a plurality of such compoundsand reference to “the assay” includes reference to one or more assaysand equivalents thereof known to those skilled in the art.

“Alkyl” refers to an unbranched or branched saturated hydrocarbon chain.As used herein, alkyl has 1 to 20 carbon atoms (i.e., C₁₋₂₀ alkyl), 1 to8 carbon atoms (i.e., C₁₋₈ alkyl), 1 to 6 carbon atoms (i.e., C₁₋₆alkyl), or 1 to 4 carbon atoms (i.e., C₁₋₄ alkyl). Examples of alkylgroups include methyl, ethyl, propyl, isopropyl, n-butyl, sec-butyl,iso-butyl, tert-butyl, pentyl, 2-pentyl, isopentyl, neopentyl, hexyl,2-hexyl, 3-hexyl, and 3-methylpentyl. When an alkyl residue having aspecific number of carbons is named by chemical name or identified bymolecular formula, all positional isomers having that number of carbonsmay be encompassed; thus, for example, “butyl” includes n-butyl (i.e.,—(CH₂)₃CH₃), sec-butyl (i.e., —CH(CH₃)CH₂CH₃), isobutyl (i.e.,—CH₂CH(CH₃)₂) and tert-butyl (i.e., —C(CH₃)₃); and “propyl” includesn-propyl (i.e., —(CH₂)₂CH₃) and isopropyl (i.e., —CH(CH₃)₂).

“Cyano” refers to the group —CN.

“Halo” refers to —F, —Cl, —Br, —I.

Certain commonly used alternative chemical names may be used. Forexample, a divalent group such as a divalent “alkyl” group, a divalent“aryl” group, etc., may also be referred to as an “alkylene” group or an“alkylenyl” group, an “arylene” group or an “arylenyl” group,respectively. Also, unless indicated explicitly otherwise, wherecombinations of groups are referred to herein as one moiety, e.g.,arylalkyl, the last mentioned group contains the atom by which themoiety is attached to the rest of the molecule.

The terms “optional” or “optionally” means that the subsequentlydescribed event or circumstance may or may not occur, and that thedescription includes instances where said event or circumstance occursand instances in which it does not. Also, the term “optionallysubstituted” refers to any one or more hydrogen atoms on the designatedatom or group may or may not be replaced by a moiety other thanhydrogen. “Optionally substituted” may be zero to the maximum number ofpossible substitutions, and each occurrence is independent. When theterm “substituted” is used, then that substitution is required to bemade at a substitutable hydrogen atom of the indicated substituent. Anoptional substitution may be the same or different from a (required)substitution.

When a moiety is “optionally substituted,” and reference is made to ageneral term, such as any “alkyl,” “alkenyl,” “alkynyl,” “haloalkyl,”“cycloalkyl,” “aryl” or “heteroaryl,” then the general term can refer toany antecedent specifically recited term, such as (C₁₋₃ alkyl), (C₄₋₆alkyl), —O(C₁₋₄ alkyl), (C₃₋₁₀ cycloalkyl), O—(C₃₋₁₀ cycloalkyl) and thelike. For example, “any aryl” includes both “aryl” and as well asexamples of aryl, such as phenyl or naphthyl and the like. Also, theterm “any heterocyclyl” includes heterocyclyls, such as oxetanyl,tetrahydropyranyl, morpholino, piperidinyl and the like. In the samemanner, the term “any heteroaryl” includes heteroaryls, such aspyridine, pyridazine, thiazole, thiadiazole, quinoline and the like.

Some of the compounds exist as tautomers. Tautomers are in equilibriumwith one another. For example, amide containing compounds may exist inequilibrium with imidic acid tautomers. Regardless of which tautomer isshown, and regardless of the nature of the equilibrium among tautomers,the compounds are understood by one of ordinary skill in the art tocomprise both amide and imidic acid tautomers. Thus, the amidecontaining compounds are understood to include their imidic acidtautomers. Likewise, the imidic acid containing compounds are understoodto include their amide tautomers.

Any formula or structure given herein, is also intended to representunlabeled forms as well as isotopically labeled forms of the compounds.Isotopically labeled compounds have structures depicted by the formulasgiven herein except that one or more atoms are replaced by an atomhaving a selected atomic mass or mass number. Examples of isotopes thatcan be incorporated into compounds of the disclosure include isotopes ofhydrogen, carbon, nitrogen, oxygen, phosphorous, fluorine and chlorine,such as, but not limited to ²H (deuterium, D), ³H (tritium), ¹¹C, ¹³C,¹⁴C, ¹⁵N, ¹⁸F, ¹⁵O, ¹⁸O, ³F, ³²F, ³⁵S, ³⁶Cl and ¹²⁵I. Variousisotopically labeled compounds of the present disclosure, for examplethose into which radioactive isotopes such as ³H, ¹³C and ¹⁴C areincorporated. Such isotopically labelled compounds may be useful inmetabolic studies, reaction kinetic studies, detection or imagingtechniques, such as positron emission tomography (PET) or single-photonemission computed tomography (SPECT) including drug or substrate tissuedistribution assays or in radioactive treatment of patients.

The disclosure also includes “deuterated analogues” of compounds ofFormula I in which from 1 to n hydrogens attached to a carbon atomis/are replaced by deuterium, in which n is the number of hydrogens inthe molecule. Such compounds exhibit increased resistance to metabolismand are thus useful for increasing the half-life of any compound ofFormula I when administered to a mammal, particularly a human. See, forexample, Foster, “Deuterium Isotope Effects in Studies of DrugMetabolism,” Trends Pharmacol. Sci. 5(12):524-527 (1984). Such compoundsare synthesized by means well known in the art, for example by employingstarting materials in which one or more hydrogens have been replaced bydeuterium.

Deuterium labelled or substituted therapeutic compounds of thedisclosure may have improved DMPK (drug metabolism and pharmacokinetics)properties, relating to distribution, metabolism and excretion (ADME).Substitution with heavier isotopes such as deuterium may afford certaintherapeutic advantages resulting from greater metabolic stability, forexample increased in vivo half-life, reduced dosage requirements and/oran improvement in therapeutic index. An ¹⁸F labeled compound may beuseful for PET or SPECT studies. Isotopically labeled compounds of thisdisclosure and prodrugs thereof can generally be prepared by carryingout the procedures disclosed in the schemes or in the examples andpreparations described below by substituting a readily availableisotopically labeled reagent for a non-isotopically labeled reagent. Itis understood that deuterium in this context is regarded as asubstituent in the compound of Formula I.

The concentration of such a heavier isotope, specifically deuterium, maybe defined by an isotopic enrichment factor. In the compounds of thisdisclosure any atom not specifically designated as a particular isotopeis meant to represent any stable isotope of that atom. Unless otherwisestated, when a position is designated specifically as “H” or “hydrogen”,the position is understood to have hydrogen at its natural abundanceisotopic composition. Accordingly, in the compounds of this disclosureany atom specifically designated as a deuterium (D) is meant torepresent deuterium.

In many cases, the compounds of this disclosure are capable of formingacid and/or base salts by virtue of the presence of amino and/orcarboxyl groups or groups similar thereto.

Provided are also pharmaceutically acceptable salts, hydrates, solvates,tautomeric forms, polymorphs, and prodrugs of the compounds describedherein. “Pharmaceutically acceptable” or “physiologically acceptable”refer to compounds, salts, compositions, dosage forms and othermaterials which are useful in preparing a pharmaceutical compositionthat is suitable for veterinary or human pharmaceutical use.

The term “pharmaceutically acceptable salt” of a given compound refersto salts that retain the biological effectiveness and properties of thegiven compound, and which are not biologically or otherwise undesirable.“Pharmaceutically acceptable salts” or “physiologically acceptablesalts” include, for example, salts with inorganic acids and salts withan organic acid. In addition, if the compounds described herein areobtained as an acid addition salt, the free base can be obtained bybasifying a solution of the acid salt. Conversely, if the product is afree base, an addition salt, particularly a pharmaceutically acceptableaddition salt, may be produced by dissolving the free base in a suitableorganic solvent and treating the solution with an acid, in accordancewith conventional procedures for preparing acid addition salts from basecompounds. Those skilled in the art will recognize various syntheticmethodologies that may be used to prepare nontoxic pharmaceuticallyacceptable addition salts. Pharmaceutically acceptable acid additionsalts may be prepared from inorganic and organic acids. Salts derivedfrom inorganic acids include hydrochloric acid, hydrobromic acid,sulfuric acid, nitric acid, phosphoric acid, and the like. Salts derivedfrom organic acids include acetic acid, propionic acid, glycolic acid,pyruvic acid, oxalic acid, malic acid, malonic acid, succinic acid,maleic acid, fumaric acid, tartaric acid, citric acid, benzoic acid,cinnamic acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid,p-toluene-sulfonic acid, salicylic acid, and the like. Likewise,pharmaceutically acceptable base addition salts can be prepared frominorganic and organic bases. Salts derived from inorganic bases include,by way of example only, sodium, potassium, lithium, ammonium, calciumand magnesium salts. Salts derived from organic bases include, but arenot limited to, salts of primary, secondary and tertiary amines, such asalkyl amines (i.e., NH₂(alkyl)), dialkyl amines (i.e., HN(alkyl)₂),trialkyl amines (i.e., N(alkyl)₃), substituted alkyl amines (i.e.,NH₂(substituted alkyl)), di(substituted alkyl) amines (i.e.,HN(substituted alkyl)₂), tri(substituted alkyl) amines (i.e.,N(substituted alkyl)₃), alkenyl amines (i.e., NH₂(alkenyl)), dialkenylamines (i.e., HN(alkenyl)₂), trialkenyl amines (i.e., N(alkenyl)₃),substituted alkenyl amines (i.e., NH₂(substituted alkenyl)),di(substituted alkenyl) amines (i.e., HN(substituted alkenyl)₂),tri(substituted alkenyl) amines (i.e., N(substituted alkenyl)₃, mono-,di- or tri-cycloalkyl amines (i.e., NH₂(cycloalkyl), HN(cycloalkyl)₂,N(cycloalkyl)₃), mono-, di- or tri-arylamines (i.e., NH₂(aryl),HN(aryl)₂, N(aryl)₃), or mixed amines, etc. Specific examples ofsuitable amines include, by way of example only, isopropylamine,trimethyl amine, diethyl amine, tri(iso-propyl) amine, tri(n-propyl)amine, ethanolamine, 2-dimethylaminoethanol, piperazine, piperidine,morpholine, N-ethylpiperidine, and the like.

The term “substituted” means that any one or more hydrogen atoms on thedesignated atom or group is replaced with one or more substituents otherthan hydrogen, provided that the designated atom's normal valence is notexceeded. The one or more substituents include, but are not limited to,alkyl, alkenyl, alkynyl, alkoxy, acyl, amino, amido, amidino, aryl,azido, carbamoyl, carboxyl, carboxyl ester, cyano, guanidino, halo,haloalkyl, haloalkoxy, heteroalkyl, heteroaryl, heterocyclyl, hydroxy,hydrazino, imino, oxo, nitro, alkylsulfinyl, sulfonic acid,alkylsulfonyl, thiocyanate, thiol, thione, or combinations thereof.Polymers or similar indefinite structures arrived at by definingsubstituents with further substituents appended ad infinitum (e.g., asubstituted aryl having a substituted alkyl which is itself substitutedwith a substituted aryl group, which is further substituted by asubstituted heteroalkyl group, etc.) are not intended for inclusionherein. Unless otherwise noted, the maximum number of serialsubstitutions in compounds described herein is three. For example,serial substitutions of substituted aryl groups with two othersubstituted aryl groups are limited to ((substituted aryl)substitutedaryl) substituted aryl. Similarly, the above definitions are notintended to include impermissible substitution patterns (e.g., methylsubstituted with 5 fluorines or heteroaryl groups having two adjacentoxygen ring atoms). Such impermissible substitution patterns are wellknown to the skilled artisan. When used to modify a chemical group, theterm “substituted” may describe other chemical groups defined herein.Unless specified otherwise, where a group is described as optionallysubstituted, any substituents of the group are themselves unsubstituted.For example, in some embodiments, the term “substituted alkyl” refers toan alkyl group having one or more substituents including hydroxyl, halo,alkoxy, cycloalkyl, heterocyclyl, aryl, and heteroaryl. In otherembodiments, the one or more substituents may be further substitutedwith halo, alkyl, haloalkyl, hydroxyl, alkoxy, cycloalkyl, heterocyclyl,aryl, or heteroaryl, each of which is substituted. In other embodiments,the substituents may be further substituted with halo, alkyl, haloalkyl,alkoxy, hydroxyl, cycloalkyl, heterocyclyl, aryl, or heteroaryl, each ofwhich is unsubstituted. One skilled in the art will recognize thatsubstituents and other moieties of the compounds of the generic formulaherein should be selected in order to provide a compound which issufficiently stable to provide a pharmaceutically useful compound whichcan be formulated into an acceptably stable pharmaceutical composition.Compounds which have such stability are contemplated as falling withinthe scope of the present invention. It should be understood by oneskilled in the art that any combination of the definitions andsubstituents described above should not result in an inoperable speciesor compound.

As used herein, “pharmaceutically acceptable carrier” or“pharmaceutically acceptable excipient” includes any and all solvents,dispersion media, coatings, antibacterial and antifungal agents,isotonic and absorption delaying agents and the like. The use of suchmedia and agents for pharmaceutically active substances is well known inthe art. Except insofar as any conventional media or agent isincompatible with the active ingredient, its use in the therapeuticcompositions is contemplated. Supplementary active ingredients can alsobe incorporated into the compositions.

A “solvate” is formed by the interaction of a solvent and a compound.Solvates of salts of the compounds described herein are also provided.Hydrates of the compounds described herein are also provided.

Pharmaceutical Compositions

While it is possible for the active ingredients to be administered aloneit may be preferable to present them as pharmaceutical formulations(compositions). The formulations, both for veterinary and for human use,of the invention comprise at least one active ingredient, as abovedefined, together with one or more acceptable carriers therefor andoptionally other therapeutic ingredients. The carrier(s) must be“acceptable” in the sense of being compatible with the other ingredientsof the formulation and physiologically innocuous to the recipientthereof.

The formulations include those suitable for the foregoing administrationroutes. The formulations may conveniently be presented in unit dosageform and may be prepared by any of the methods well known in the art ofpharmacy. Techniques and formulations generally are found in Remington'sPharmaceutical Sciences (Mack Publishing Co., Easton, Pa.). Such methodsinclude the step of bringing into association the active ingredient withinactive ingredients (e.g., a carrier, pharmaceutical excipient, etc.)which constitutes one or more accessory ingredients. In general theformulations are prepared by uniformly and intimately bringing intoassociation the active ingredient with liquid carriers or finely dividedsolid carriers or both, and then, if necessary, shaping the product.

In certain embodiments, formulations suitable for oral administrationare presented as discrete units such as capsules, cachets or tabletseach containing a predetermined amount of the active ingredient.

In certain embodiments, the pharmaceutical formulations include one ormore compounds of the invention together with one or morepharmaceutically acceptable carriers or excipients and optionally othertherapeutic agents. Pharmaceutical formulations containing the activeingredient may be in any form suitable for the intended method ofadministration. When used for oral use for example, tablets, troches,lozenges, aqueous or oil suspensions, dispersible powders or granules,emulsions, hard or soft capsules, syrups or elixirs may be prepared.Compositions intended for oral use may be prepared according to anymethod known to the art for the manufacture of pharmaceuticalcompositions and such compositions may contain one or more agentsincluding sweetening agents, flavoring agents, coloring agents andpreserving agents, in order to provide a palatable preparation. Tabletscontaining the active ingredient in admixture with non-toxicpharmaceutically acceptable excipient which are suitable for manufactureof tablets are acceptable. These excipients may be, for example, inertdiluents, such as calcium or sodium carbonate, lactose, lactosemonohydrate, croscarmellose sodium, povidone, calcium or sodiumphosphate; granulating and disintegrating agents, such as maize starch,or alginic acid; binding agents, such as cellulose, microcrystallinecellulose, starch, gelatin or acacia; and lubricating agents, such asmagnesium stearate, stearic acid or talc. Tablets may be uncoated or maybe coated by known techniques including microencapsulation to delaydisintegration and adsorption in the gastrointestinal tract and therebyprovide a sustained action over a longer period. For example, a timedelay material such as glyceryl monostearate or glyceryl distearatealone or with a wax may be employed.

The amount of active ingredient that is combined with the inactiveingredients to produce a dosage form will vary depending upon the hosttreated and the particular mode of administration. For example, in someembodiments, a dosage form for oral administration to humans containsapproximately 1 to 1000 mg of active material formulated with anappropriate and convenient amount of carrier material (e.g., inactiveingredient or excipient material). In certain embodiments, the carriermaterial varies from about 5 to about 95% of the total compositions(weight:weight). In some embodiments, the pharmaceutical compositionsdescribed herein contain about 1 to 800 mg, 1 to 600 mg, 1 to 400 mg, 1to 200 mg, 1 to 100 mg or 1 to 50 mg of the compound of Formula I, or apharmaceutically acceptable salt thereof. In some embodiments, thepharmaceutical compositions described herein contain not more than about400 mg of the compound of Formula I. In some embodiments, thepharmaceutical compositions described herein contain about 100 mg of thecompound of Formula I, or a pharmaceutically acceptable salt thereof.

It should be understood that in addition to the ingredients particularlymentioned above the formulations disclosed herein may include otheragents conventional in the art having regard to the type of formulationin question, for example those suitable for oral administration mayinclude flavoring agents.

Veterinary compositions comprising at least one active ingredient asabove defined together with a veterinary carrier are further provided.

Veterinary carriers are materials useful for the purpose ofadministering the composition and may be solid, liquid or gaseousmaterials which are otherwise inert or acceptable in the veterinary artand are compatible with the active ingredient. These veterinarycompositions may be administered orally, parenterally or by any otherdesired route.

Effective dose of active ingredient depends at least on the nature ofthe condition being treated, toxicity, whether the compound is beingused prophylactically (lower doses), the method of delivery, and thepharmaceutical formulation, and will be determined by the clinicianusing conventional dose escalation studies.

Routes of Administration

One or more compounds of Formula I (herein referred to as the activeingredients), or a pharmaceutically acceptable salt thereof, areadministered by any route appropriate to the condition to be treated.Suitable routes include oral, rectal, nasal, topical (including buccaland sublingual), vaginal and parenteral (including subcutaneous,intramuscular, intravenous, intradermal, intrathecal and epidural), andthe like. It will be appreciated that the preferred route may vary withfor example the condition of the recipient. An advantage of thecompounds of this invention is that they are orally bioavailable and canbe dosed orally. Accordingly, in one embodiment, the pharmaceuticalcompositions described herein are oral dosage forms. In certainembodiments, the pharmaceutical compositions described herein are oralsolid dosage forms.

Biological Assays

Biological assays were conducted to measure activity against TNFα andIRAK4. As summarized in Table 3, the test compounds are inhibitors ofIRAK4.

IRAK4 Monocyte TNFα Cell Based Assay Procedure:

Cryopreserved human monocytes (Stem Cell Technologies) were thawed,diluted in RPMI with GlutaMAX™ (Gibco® 200 mM L-alanyl-L-glutamine) (10mM HEPES, 1× Pen-Strep, 55 μM B-mercaptoethanol, 1 mM Sodium pyruvate)media containing 10% FBS to 0.125×10⁶ cells/ml and recovered at 37° C.for 2 hours. The cell suspension was then plated at a density of 5,000cells/well onto black 384 well Greiner clear bottom plates. Plates werepre-spotted with test compounds and serially diluted in DMSO where 40nL/well were delivered using the Echo 550 acoustic liquid dispenser(Labcyte®) for a final DMSO concentration of 0.1%. Plated cells weretreated with compound for 1 hour at 37° C. Cells were then stimulatedwith 50 pg/ml of LPS (Sigma) excluding outside columns of plate used forunstimulated cell control wells. Cells were incubated for an additional4 hours at 37° C. Cells were then spun out of the media and 5 μl ofsample were taken and analyzed for total TNFα content using the TR-FRETHuman TNFα detection system (CisBio). This system utilizes two labeledantibodies (cryptate and XL665) that bind to two different epitopes ofthe TNFα molecule and produce FRET signal proportional to theconcentration of TNFα in the sample. Detection antibodies are mixed50:50 and 5 μL were dispensed into each well. Plates were covered withclear seals and incubated at room temp overnight. The following morningplates were read using an Envision 2103 Multilabeled reader(PerkinElmer) with excitation/emission/FRET emission at 340 nm/615nm/665 nm, respectively. Fluorescence intensities at 615 nm and 665 nmemission wavelengths were expressed as a ratio (665 nm/615 nm). Percentof control was calculated as follows:

%Control=100×(Ratio_(Sample)−Ratio_(0% stimuiation))/(Ratio_(100% Stimulation)−Ratio_(0% Stimulation))

where unstimulated cells (0% stimulation) were the negative control andstimulated cells (100% stimulation) were used as the positive control.

IRAK4 Biochemical Assay Procedure:

IRAK4 enzyme (Carna Biosciences, Chuo-ku, Kobe, Japan) activity wasmeasured by detecting phosphorylated peptide substrate formation usingan antibody against the phosphorylated peptide substrate. This is atime-resolved fluorescence resonance energy transfer (TR-FRET)immunoassay, based on the STK1 KinEASE Assay (Cisbio, Bedford, Mass.).The assay was designed as a simple two-step, endpoint assay (a 5 μlenzyme reaction followed by 5 μl stop and detect Solution) performed inProxiPlate-384 Plus plates (Perkin Elmer, Waltham, Mass.).Staurosporine, a non-selective kinase inhibitor was used as a positivecontrol. Compounds diluted in DMSO were spotted into 384 well platesusing a Labcyte® Echo 550 Liquid Handling System prior to addition ofIRAK4 enzyme and peptide substrate. Reaction solutions were deliveredusing a Multi-Flo (Bio-Tek Instruments). The enzyme and peptide solutionwas incubated with compound for 15 minutes at room temp before thereaction was initiated by the addition of ATP. The standard 5 μlreaction mixture contained 500 μM ATP, 2 μM peptide (STK1 Peptide), 0.75nM of IRAK4 in reaction buffer (50 mM HEPES, pH 7.0, 0.02% NaN₃, 0.01%BSA, 0.1 mM Orthovanadate, 5 mM MgCl₂, 0.025% NP-40, 1 mM DTT). After120 min of incubation at room temperature, 5 μl of Stop and DetectSolution (1:100 Cryptate labeled anti-phosphorylated peptide antibodysolution and 125 nM Tracer in a 50 mM HEPES pH 7.0 detection buffercontaining sufficient EDTA) was added. The plate was then furtherincubated for 60 minutes at room temperature and read on Envision 2103Multilabeled reader (PerkinElmer) with excitation/emission/FRET emissionat 340 nm/615 nm/665 nm, respectively. Fluorescence intensities at 615nm and 665 nm emission wavelengths were expressed as a ratio (665 nm/615nm). Percentage of inhibition was calculated as below:

%Inhibition=100×(Ratio_(Sample)−Ratio_(0% Inhibition))/(Ratio_(100% Inhibition)−Ratio_(0% Inhibition))

The 0% inhibition value comes from control wells lacking inhibitor. The100% inhibition value comes from control wells containing a saturatingamount of known inhibitor staurosporine.

Hepatic Stability:

Metabolic Stability in Cryopreserved Hepatocytes:

Complete HT medium was prepared by the addition of 1 mL TorpedoAntibiotic Mix to 45 mL of InVitroGRO™ HT medium. Supplemented KHBmedium consisted of KrebsHenseleit buffer with amikacin (84 μg/mL),calcium chloride (1 mM), gentamicin (84 μg/mL), HEPES (20 mM), heptanoicacid (4.2 μM) and sodium bicarbonate (28.5 mM) and the pH was adjustedto 7.4 at 37° C. using 1 M NaOH or 1 M HCl. The human cryopreservedhepatocytes were pooled from ten adult donors (Celsis, Lot: HBZ).

Vials containing cryopreserved hepatocytes were removed from liquidnitrogen and immediately immersed in a 37° C. water bath. The vials wereshaken gently until the contents had thawed and were then immediatelyemptied into 48 mL of pre warmed Complete HT Medium in a 50 mL conicaltube. Cells remaining in the vial were resuspended with 1.0 mL of prewarmed Complete HT Medium and added to the conical tube. The tube wascapped and then gently inverted several times to resuspend thehepatocytes. The cell suspension was centrifuged at 50× g at roomtemperature for 5 minutes and the supernatant discarded. The cell pelletwas loosened by gently swirling the centrifuge tube and Supplemented KHBmedium was added to obtain a target density of 2×10⁶ cells/mL. The totalcell count and the proportion of viable cells were determined by TrypanBlue dye exclusion using a hemocytometer.

For incubations, aliquots of hepatocyte suspension (250 μl containing500,000 cells) were added to 250 μl of 2 μM test compound or metabolicstability controls in supplemented KHB in duplicate wells in a 24-wellplate. Final concentration in the incubations were 1×10⁶ cells/mL and 1μM test compound. 7-Hydroxycoumarin and testosterone, compounds known tobe efficiently metabolized by hepatocytes, were used as positivecontrols in parallel incubations (2 μM final concentration of eachcompound). The incubation was carried out with gentle shaking at 37° C.under a humid atmosphere of 95% air/5% CO₂ (v/v). Aliquots (50 μL) wereremoved after 0, 1, 3, and 6 hours and added to 100 μl IS/Q quenchingsolution. After termination, 150 μl of water was added, the plates werecentrifuged at 3000×g for 10 min, and aliquots of the supernatant wereanalyzed on a Micromass Quattro Premier mass spectrometer coupled to anAgilent 1200 Series HPLC system with a Leap Technologies HTC PALautosampler as described below.

A stock solution of test compound in dimethyl sulfoxide (DMSO) having afinal concentration of 10 mM was prepared and used in all experiments.

Commercially available chemicals were obtained from Sigma-Aldrich (St.Louis, Mo.) and VWR (West Chester, Pa.). The cell culture medium (CCM)was Gibco Dulbecco's Modified Eagle Medium (DMEM) with 10% (v/v) fetalbovine serum.

Equilibrium Dialysis Assay:

Pooled plasma (from at least 3 males and 3 females) was from human,beagle dog, Sprague-Dawley rat, cynomolgus monkey, and rhesus monkey.Sodium EDTA was used as the anticoagulant.

Competitive equilibrium dialysis was conducted at 37° C. using humanplasma versus with CCM containing 10% of FBS, both sides of matrixspiked with sample at final concentrations of 2 μM. Prior to the study,dialysis membrane was soaked for approximately one hour in 0.133 Mphosphate buffer, pH 7.4. Spiked plasma (1 mL) and CCM (1 mL) wereplaced into opposite sides of the assembled dialysis cells. Forassessment of recovery, after the 24-hour equilibration period in a 37°C. water bath, plasma samples were drained into pre-weighedpolypropylene tubes containing 1 mL of CCM (without compound) and CCMsamples were drained into pre-weighed tubes containing 1 mL of relatedblank plasma. Post-dialysis plasma and CCM weights were measured andrecorded for calculations.

pK_(a) Determinations:

Sample Preparation: A stock solution of test compound in dimethylsulfoxide (DMSO) having a final concentration of 10 mM was prepared andused in all experiments. The DMSO stocks were thawed, spun, andsonicated in a 40° C. water bath to facilitate dissolution.

pK_(a) Analysis: The 10 mM DMSO stock solutions were diluted 100 foldwith 10 mM HCl for a final compound concentration of 100 μM and 1% DMSO.The compounds were then transferred into 24 consecutive wells of a 96well PCR plate for analysis with the aqueous method. For compounds thatdid not give high quality data in the aqueous method, the 10 mM DMSOstock solutions were diluted 100 fold with 2 mM HCl and methanol, suchthat the final concentration of methanol was 60%, compound concentrationwas 100 μm, and DMSO concentration was 1%. The compounds weretransferred into 24 consecutive wells of a 96 well plate for analysisusing the co-solvent method.

Analysis: All data was obtained using a pKa PRO Analyzer (AATI, Ames,Iowa). For the aqueous method, an electrophoretic separation isperformed in parallel across 24 different pH values, providing a directmeasure of overall compound charge vs. pH. The compounds are detected byUV at 228 nm. The average pH spacing between buffer points is 0.4 pHunits covering a typical pH range of 1.7-11.2.

The co-solvent method is suitable for analysis of compounds possessinglow aqueous solubility (typically a predicted intrinsic solubility of<10 μg/ml). The average pH spacing between buffer points is 0.4 pH unitscovering a pH range of 1.7-11.2. Four consecutive CE runs are performedfor each compound starting with 60% co-solvent buffers and decreasing to30% co-solvent buffers.

Norfloxacin is used as a daily performance-indicating standard.

Calculation of Results: The total number of pKa values is predicted byrelating mobility and compound molecular weight using pKa Estimator®software (AATI, Ames, Iowa).

Automated hERG Assay at Charles River—Cleveland (Formerly ChanTest)

The FASTPatch® Assay (Charles River,) was used to examine the in vitroeffects of various compounds on the cloned hERG potassium channelencoded by the KCNH2 gene and stably expressed in HEK293T cells.Vehicle, test and control article formulations were prepared by dilutingDMSO stock solutions in HB-PS (HEPES-buffered physiological salinesolution), and were delivered to cells via the QPatch robot pipettingsystem to a final concentration of 0.3% DMSO. Test compound finalconcentrations of 0.3, 1, 3, 10 and 30 uM were applied to cells (n 3,where n=the number of cells/concentration) in ascending order in atleast three minute intervals separated by solution exchange. Thepositive control, 50 nM Cisparide, was applied in the same manner. Cellmembrane currents were recorded at room temperature with up to 48parallel patch clamp amplifiers in the QPatch HT® or QPatch HTX® system,and only cells with validated whole-cell recordings (seal resistance≥200 MΩ and leak current ≤25% channel current) were used. Onset andblock of hERG current was measured using a stimulus voltage patternconsisting of a 500 ms prepulse to −40 mV, a 2-second activating pulseto +40 mV, followed by a 2-second test pulse to −40 mV. The pulsepattern was repeated continuously at 10-second intervals from a holdingpotential of −80 mV. TurboSol analysis for test compound solubility wasperformed for each concentration tested using a Nephelostar readermeasuring light scatter from a 635 nm laser source. Based on validationexperiments, light scatter above four times the background level wasconsidered an indication of the presence of particles in suspension.
